To aZZ- whom t may concern.'

Be it known that I, RUSSELL PQSGHUYLER, a citizen of the United States, residing at Chicago, in the county of Cook and State'of Illinois, have invented certain new. and .useful Improvements in Lubricating Devices," of which the following is -a description.

My invention belongs to that general class of devices intended for use inl lubricating moving part-s, having impulsive or vibrating action, and particularly in which the move*` ment and operation of the lubricating device;4 are practically automatic." To this end myv invention consists of the novel construction, arrangement and combination of parts herein shownand described, and more particularly pointed out in the claims.

In the drawings, whereinlike referencev characters indicate like or' corresponding parts,

Figure 1 is a vertical section through one form of my device;

Fig. 2 is a section Fig. 1;

Fig. 3 is a similar section online 3-3 of Figgl;

Fig. 4 is a similar Fig. 1;

Fig. 5 isa section on line 5 5 Fig. 6 is a vertical modified form of my Fig. 7 is a section line 7-7 of Figf;

Fig. 8 is a section taken on line'S-S of Fig.l 6,'and

Fig. 9 is a sectionline '9`9 of Fig. 6. f

In the drawings, l indicates a lubricator cup provided with a vertically adjustable stem 2 carrying on its lowerend a needle valve 3, controlling. the passage of a lubri-l cant through fa duct'4 to the chamber. The chamber 5 is. provided withla suitable valve seat 6, and the reduced portion 7 eX- tends from the valve seat into the enlarged sightl chamber 8. At the lower end of the chamber 8 an'upwardly seating valve seat 9 is provided, formed on the upper face of the chamber 10, the lubricant passing from s the chamber 10 through the various open ings 11 into the conducting pipev12. A peculiarly shaped conical part 13has adjustably connected to its upperpart avalve 14, provided with a seat 15, `cooperating 'with the valve seat 6 A neck 16 connects the valve thereof on line 2--2 of section'online4-4 of of Fig. '1; section 'of a slightly improved device;

taken substantially on taken substantially on through the will thus be seen that as the A14 to the part 13, as shown. A second coniupper surface of the part 13 cause the lubricantto iow down to the point on the part 13, and from thence drop downward in view sight openings upon the valve 17. In the preferred yconstruction a wall'or rim 21 is raised about the upper face of the part 13, so that as the lubricant drops down thereon will be confined to the upper face of the part and pass through the openings 20, as

stated. The valve 14 is preferably made substantially like an ordinary screw, having :screw-threaded connection at its lower end with the part 13, whereby it may be longitudinally adjustable in relation to said part, asdesired. Y

Fig. G shows a slightly modified form of my improved device, inwhichthe receptacle is provided with an air tube 22, which at the lower end connects with the duct 23, which reaches to the chamberl 8, while the valve 24 corresponding to the valve 17 in Fig. 1, is provided with one or more apertures 25, permittingthe air to pass therethrough. It

device is operated, provision is made for the passage of a certain quantity ofair to 'prevent' a partial vacuum in the cup 1, lor `other part, which might in some cases interfere with steady and regular operation of the device. In both casesV I prefer to use a removable plate 26 below the valves 9 or 24,'as the size and number of openings therethrough tend to regulate the vaporization of the lubricant as delivered, as wellas theadmission of air to the device. Thus a. plurality of such plates may be provided with a varying of apertures` therein, and of varying sizes, and the particular plate usedv that may be found are suitably connected,

from the walls of the throat 7, it i which the lubricator is attachedV causes the valve to be slightly lifted at each operation,

' permitting a small quantity of the lubricant to pass by the valve 14, and thence down part 13, dropping upon the top of the valve 17. Here it is distributed, owing to the coni- Vcal shape of the Vvalve into a thin film, and is it may be desirable to regulate the passage whereby the two valves form a unitary` ci? vthe Vfluid therethrough, thereby to a Vgreater or Vless extent controlling they vaporizing of the lilm or oil as it is delivered to said part. The valve 14 being adjustable in relation to the part 13, the needle valve 3 being also adjustable, it is obvious that the quantity of the liuid passing through the valve canbe readily regulated Vas desired.

The device being once' adjusted tothe cooperating machine, itis not necessary to manipulate valves when the machine is stopped. ln practice it is found that the device is substantially automatic in'this respect.

Having thus described myinvention, it is obvious thatl various immaterial modifications may be made without departing Jfrom the spirit of my invention; hence I do not wish to be understood as limiting myseli:l to the exact form, construction, arrangement or combination of parts herein shown and described, or` uses mentioned.-
